Is it normal to have pregnancy symptoms on mirena? I had my IUD inserted on 10/09/2014 and have been having sex without any other protection since my check up to make sure it was in place. This past week and a half I ve noticed a few things like My breasts have gotten bigger and softer/mushy, I ve had cramps in a U shape around my lower abdomen, Nausea w/some vomiting, Gas, frequent urination and more number 2s than usual, bloating, I ve also been extremely tired... I took a hpt 3 days ago but it was negative, I m just wondering is this normal or could I possibly be pregnant?
